MCLEAN, VA – (BUSINESSWIRE) – August 10, 2009, ATS Corporation (“ATSC” or the “Company”) (OTCBB:ATCT), a leading information technology company that delivers innovative technology solutions to government and commercial organizations, today announced that it is adopting a plan under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in connection with its previously announced stock repurchase program. In the 10b5-1 plan, the Board of Directors has authorized the repurchase of up to $1.5 million of the Company’s common stock over the next two years, which is a portion of the total repurchase amount approved by the Board on February 11, 2009 of the lesser of $3.0 million or 2.0 million shares. The 10b5-1 plan will facilitate purchases of the Company’s common shares and assist with compliance with Rule 10b-18 under the Exchange Act. A plan under Rule 10b5-1 permits shares to be repurchased when the Company might otherwise be precluded from doing so under insider trading laws. Purchases of common shares under the 10b5-1 plan will be subject to specified parameters and certain price, volume and timing constraints. Accordingly, there can be no assurance as to how many common shares will be purchased. In addition, the repurchase program may be suspended or discontinued at any time. Common stock acquired though the repurchase program will be held as treasury shares and may be used for general corporate purposes, including reissuances in connection with acquisitions, employee stock option exercises or other employee stock plans. The Company currently has approximately 22.7 million shares outstanding, which exclude any shares issuable upon the exercise of the Company’s outstanding warrants, expiring in October of this year, to purchase approximately 3 million shares of common stock at an exercise price of $5.00 per share.

“We continue to believe that the current market value of our shares do not accurately reflect the underlying value of the Company,” said Ed Bersoff, ATSC President and Chief Executive Officer. “Furthermore, we have decided to use a 10b5-1 plan as it gives us the ability to repurchase shares during our self-imposed blackout periods that are associated with our quarterly earnings releases, as well as other periods when there might exist material, nonpublic information that would preclude insider trading,” Bersoff added.

ATSC is a leading provider of software and systems development, systems integration, infrastructure management and outsourcing, information sharing and consulting to the Department of Defense, Federal civilian agencies, public safety and national security customers, as well as commercial enterprises. Headquartered in McLean, Virginia, the Company has more than 600 employees at 10 locations across the country.
